R-Matte Plus-3. Insulation for the Building Envelope ROOF WALL SPECIALTY

Transcription

1 Insulation for the Building Envelope ROOF WALL SPECIALTY PRODUCT DESCRIPTION Rmax R-Matte Plus-3 is an energy-efficient thermal insulation board composed of a closed-cell polyisocyanurate (polyiso) foam core bonded to reinforced aluminum foil facers on each side. While one side of the board has a reflective surface, the other side has been coated to have a non-reflective white matte surface. R-Matte Plus-3 utilizes a CFC-, HCFC- and HFC-free blowing agent that has zero Ozone Depletion Potential (ODP) and negligible Global Warming Potential (GWP). This insulation is suitable for use in walls and ceilings in new construction for commercial, residential, agricultural and industrial buildings and in thermal retrofit construction within existing buildings.

2 APPLICATION / INSTALLATION Board Orientation R-Matte Plus-3 conforms to the physical and thermal properties stated within this data sheet regardless of orientation. On exterior applications, R-Matte Plus-3 is designed to be covered with siding materials of aluminum, vinyl, fiber cement, wood or wood-based products, as well as brick, stone or stucco veneers. The white matte, non-reflective side of the board is installed facing the exterior when the exterior finish is aluminum, vinyl, fiber cement, and wood or wood-based products. The reflective side of the board is installed facing the exterior when the exterior finish is brick, stone or stucco. On interior applications, R-Matte Plus-3 may be installed with either side facing the interior. The ASHRAE Handbook of Fundamentals states that a 3/4 inch dead air space in a typical wall assembly has an R-value of 2.77 when a reflective surface is on one side. This value is in addition to the R-value of the polyiso foam. Therefore, when the R-Matte Plus-3 will be against a dead air space, additional r-value is achieved by facing the reflective side of the board towards the air space. Stud Wall Construction - R-Matte Plus-3 applied to the exterior or interior face of studs, to cover all studs, sills, plates and header constructions, provides a layer of continuous insulation (ci) over details not normally covered by insulation products. It may be secured to the framing or structural sheathing with bugle-head screws, galvanized roofing nails or common nails driven through cap washers. Quality-grade construction adhesives may also be used to secure the R-Matte Plus-3 on interior applications. Exterior facades may include brick/stone veneer, exterior siding and stucco. R-Matte Plus-3 must be covered on the interior with a minimum /2 inch gypsum wallboard interior finish that is mechanically attached. AIR / WATER RESISTIVE BARRIER Cavity Wall Construction (Brick Veneer) - R-Matte Plus-3 is an excellent cavity insulation product fitting between the masonry block and finished brick veneer of any residential or commercial project. It may be secured to the dry face of the masonry block wall with a quality grade construction adhesive. R-Matte Plus-3 can be cut to fit between masonry joint reinforcements placed to tie the brick veneer to the concrete block back-up and installed horizontally in strips to allow the wall ties to extend beyond the face of the insulation leaving the proper air spaces as required.

It may be secured to the inside face of a concrete or concrete masonry wall, over or under the furring strips, and covered with a minimum /2 inch gypsum wallboard interior finish. Adhesives, screws or nails may be used to hold the R-Matte Plus-3 in place against the wall temporarily, until the furring strips and gypsum wallboard are installed. The furring strips and gypsum wallboard must be secured with suitable screws or nails. BRICK TIES AS REQ.

3 Exterior Stucco Construction - R-Matte Plus-3 may be used as the insulative sheathing under hard coat stucco finishes. It may be secured to the studs with bugle-head screws, galvanized roofing nails or common-nails driven through cap washers. Cover the R-Matte Plus-3 with a suitable separation layer such as an organic or inorganic felt. Then, attach conventional metal wire lath and expansion joints with appropriate fasteners as dictated by the local Building Code. Rmax does not recommend the direct attachment of stucco, such as Portland cement or polymer-modified types, directly to the face of the insulation product. Consult stucco manufacturers for details. Vaulted Ceiling Construction - R-Matte Plus-3 may be applied to the inside face of the roof rafters in vaulted ceiling construction to provide a layer of continuous insulation (ci) and increase the R-value of the roof. Simply nail the R-Matte Plus-3 to the face of the rafter, cover with a minimum /2 inch gypsum wallboard and finish.

Stud walls must be properly braced for lateral loads according to the requirements of local Building Codes. STUD WALL EXTERIOR WOOD SHEATHING. Stud walls must be properly braced for lateral loads Stucco Construction 06 Re-Siding Construction - R-Matte Plus-3 may be used in retrofit construction provided the existing siding is sound and solidly attached. It is secured with galvanized nails of sufficient length to penetrate the old sidings, sheathings below and at least one inch into the existing wall studs. Then, cover the R-Matte Plus-3 with a suitable new siding of aluminum, vinyl, fiber cement, wood or wood fiber based products. FOUNDATION EXISTING SHEATHING AND SIDING SEE NOTE # AIR / WATER RESISTIVE BARRIER EXTERIOR SIDING METAL FLASHING. Existing siding must be inspected and re-nailed to provide for solid back-up to attach new sheathing and siding materials. Deteriorated or rotted areas of existing siding must be removed and replaced to restore original thickness. 2. Stud walls must be properly braced for lateral loads Attics and Crawl Spaces - R-Matte Re-Siding Plus-3 may Construction be applied to the 03interior R-MATTE PLUS-3 Exterior Application A.00 face of stud walls or roof rafters within attics and crawl spaces to provide a layer of continuous insulation (ci). Simply nail the R-Matte Plus-3 to the framing members and cover with an approved ignition barrier such as 3/8 inch gypsum wallboard or /4 inch wood structural panel, particle board or hardboard. LIMITATIONS Stud Wall & Vaulted Ceiling Construction 07 R-MATTE PLUS-3 Interior Application A.00 R-Matte Plus-3 is not recommended, nor warranted, for use as a commercial roof insulation directly under membrane systems. Consult Rmax Sales for suitable commercial roof insulation products. R-Matte Plus-3 is not a structural panel. It must not be used as a nailing base for any other building products. Furthermore, stud walls insulated with R-Matte Plus-3 must be properly braced for lateral loads according to the requirements of local Building Codes. WARNING DO NOT leave R-Matte Plus-3 exposed. Polyiso foam is an organic material which will burn when exposed to an ignition source of sufficient heat and intensity and may contribute to flames spreading. Installations utilizing R-Matte Plus-3 must be fully protected on the interior side of the building by a thermal barrier such as a minimum of /2 inch gypsum wallboard. Masonry or concrete that is a minimum of one inch thick, plywood that is a minimum of /2 inch thick and wood that is a minimum of one inch nominal thickness may also be recognized as suitable thermal barriers. Consult your local Building Official for specific governing codes and requirements. The interior and/or exterior of the building should be protected with a suitable vapor retarder and/or a water resistive barrier, if required, based on local Building Codes and climate zone.
